Averaging down in the OTC is suicide. Averaging down assumes that the price will pop back up. If that does not happen and it just keeps settling lower and lower, simply holding and buying more will just eat up more of your account.
Gotta learn to utilize stop losses. Pull your money out if you know it is going lower. I learned this the hard way on trash ticker OWCP.
99% of penny stocks are pump and dumps, yet 100% of penny stocks pretend to be in the 1%. Contracts, patents, mergers, partnerships, and other such news are usually "too good to be true" and should be looked at in detail. The source should also be vetted.
